I've owned my lovely 2014 S5 Sportback Black Edition for a year now. I bought it with 1 previous owner, full Audi SH and lots of receipts showing no expense had been spared keeping it in tip top condition over the years. It's just turned 70k miles,
Over the last few months I've noticed a rattle under the car at low revs, usually with foot off the accelerator at low speeds in 1st gear. It sounded to me like a heatshield that was loose. I've just had it serviced and MOT'd, and was told it's the intermediate catalytic converters rattling. It sailed through the MOT, including emissions.
Is the cats going at this age/mileage common? Is it important to get them replaced sooner rather than later? Not a cheap job I think, they look to be £500 each side for after market ones - imagine Audi ones are a lot more :cry:

Thanks @Smokey Joe , hoping thats potentially a cheaper fix. Any idea on whether it's something that should be fixed ASAP or one that I can live with for a bit?
Any way to be certain it's those rather than cats? Presume the garage just listened to it from underneath with it up on the ramp

Hi @Dave Kwatro , thanks for your reply. It certainly sounds like that's what I'm hearing. It gives me more peace of mind that there's not a big bill around the corner! I'll stop worrying then and just keep listening out to check for it getting any worse.
